Observation sub peak

Beautiful clear morning on the parkway. -7 at the car at 7am. Went to N glacier on observation peak via the SE face/ east peak. West facing alpine aspects pretty wind blasted and bare up there. Upper pitch pretty wind affected, mix of dust on crust and sastrugi but lower down skied better than expected. Debris from an old size 2 noted on the SE aspect of observation peak near some cliffs. Old Debris from cornice failures observed on the N facing cirque forehead chutes. +1 at noon back at the car
